CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Ser. No. 62/739,228 filed Sep. 30, 2018, the entire contents of which are hereby incorporated by reference into this application.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present disclosure relates generally to the field of oilfield equipment; and more specifically relates to devices for introducing a ball, e.g., a drop ball, into a wellbore for activating or deactivating ball-operated equipment.

2. General Background

When exploring and completing a subterranean well for the production of oil and/or gas from underground reservoirs, several types of tubulars may be placed downhole as part of the drilling, exploration and completions process. These tubulars can include casing, tubing, pipes, liners and the like, and various types of downhole tools and other devices can be moved into or out of a wellbore by or within such tubulars.

Various types of downhole equipment can be activated and/or deactivated by balls that are dropped downhole for cooperating with such equipment. For example, a ball can be dropped from the earth's surface down through a tubular onto a seat having a diameter less than the diameter of the dropped ball. An increase in the pumped pressure can cause some element of the downhole equipment to be actuated. In general, such actuation may include actions such as the movement of a sleeve, the opening or closing of a port, the movement of a valve, the fracturing of a frangible disk, the release of elastomeric plugs, the control of downhole packers, etc. In at least some cases, the insertion of a ball into a wellbore can expose individuals to an increased risk of danger, such as by calling for workers to climb atop elevated equipment or to perform tasks in the vicinity of heavy equipment, highly pressurized fluid conduits and the like. Thus, controlled dropping of one or more balls into a wellbore can be very important, as can be minimizing the risk of injury to personnel in doing so.

The present disclosure is directed to new and useful devices, systems and methods for introducing a ball, e.g., a drop ball, into a wellbore for cooperation with ball-operated equipment.

In at least one embodiment, a system 10 according to the disclosure, such as a ball dropper system, can include one or more balls 12 and one or more ball droppers 100 for introducing one or more balls 12 into a wellbore. In at least one embodiment, a ball dropper 100 according to the disclosure can include a housing 101 for at least partially housing, enclosing or otherwise supporting one or more other components of ball dropper 100 and/or of a system 10 including ball dropper 100. Ball dropper 100 can include one or more tubes, such as pipes or other conduits, coupled to housing 101, such as for routing a ball into, out of or otherwise relative to housing 101. For example, ball dropper 100 can include a first tube 102 having an inlet 104 and an outlet 106 and adapted for loading or otherwise disposing a ball at least partially into housing 101 and a second tube 108 having an inlet 110 and an outlet 112 and adapted for routing a ball from housing 101 to a wellbore. In at least one embodiment, one or more of tubes 102, 108 can have one or more additional inlets and/or outlets (not shown), such as for receiving balls from and/or routing balls to a plurality of locations, whether separately, collectively, simultaneously or otherwise. A ball 12 can be routed into a wellbore directly or indirectly via other operation equipment coupled to a wellbore, such as conduits, valves, Christmas trees, pressure control equipment or other well components. A system 10 can include one or more of such components (not shown) and one or more ball droppers 100 coupled to or adapted to be coupled to one or more of such components, which may be or include any oilfield equipment now known or future developed and capable of facilitating or otherwise allowing travel of a ball 12 from ball dropper 100 to or into a wellbore (or vice versa).

In at least one embodiment, first tube 102 can have an outlet 106 fluidically coupled to housing 101 and second tube 108 can have an inlet 110 fluidically coupled to housing 101 for allowing a ball 12 to travel through first tube 102, into housing 101, out of housing 101, into second tube 108 and out of second tube 108, selectively, controllably or otherwise. Inlet 104 of first tube 102 can be adapted for receiving a ball 12 manually, automatically or otherwise, which can include receiving one or more balls 12 before ball dropper 100 is coupled in ball-dropping communication with a wellbore or otherwise positioned for ball dropping. One or both of first tube 102 and second tube 108 can be or include a single conduit or ball path. However, this need not be the case and, in at least one embodiment, one or more of first and second tubes 102, 108 can include a plurality of tube sections or portions coupled with one another, whether end to end or otherwise.

In at least one embodiment, ball dropper 100 can include one or more inserts 114, such as a holder or guide, for moving or at least partially supporting movement of a ball 12 between or among one or more positions. Insert 114 can be moveably associated with at least a portion of housing 101 (e.g., slideably), which can include being at least partially disposed within the housing or a portion thereof. Insert 114 can include one or more openings 115, such as a hole, through hole, slot, gap or other space, for receiving or otherwise cooperating with at least a portion of one or more balls 12 for being disposed in a wellbore. For example, insert 114 can have a position, such as a first, second or other position, wherein an opening 115 is in communication with outlet 106 of first tube 102 for receiving a ball 12 from first tube 102 into insert 114 or opening 115 and another position, such as a first, second or other position, wherein the opening 115 is in communication with inlet 110 of second tube 108 for disposing ball 12 from insert 114 or opening 115 into inlet 110 of second tube 108. Housing 101 can be adapted for allowing insert 114 to travel between or among such positions, which can include being sized for allowing at least a portion of insert 114 to travel past second tube 108 (e.g., to the left of second tube 108 as shown in the exemplary orientation of FIGS. 3-4).

Accordingly, opening 115 can be shaped and sized for receiving at least a portion of one or more balls 12, which can include any shape and size according to an implementation of the disclosure. For example, ball dropper 100 can be adapted for use with balls 12 having diameters or other major dimensions of from 1.5 inches to 3 inches, or larger or smaller. In general, ball dropper 100 can be adapted for use with any size ball 12 corresponding to the requirements of a ball-operated device with which ball dropper 100 may be utilized according to an implementation of the disclosure. In at least one embodiment, opening 115 can be cylindrical and can have a diameter equal to or greater than a corresponding ball 12, which can be or include a ball 12 having any diameter or other dimension according to an implementation of the disclosure. In such an embodiment, which is but one of many, insert 114 can have a height equal to or greater than a height or other dimension of ball 12. However, this need not be the case and numerous other configurations of insert 114 are possible. For example, insert 114 can be shorter than ball 12, which can be or include any dimension that supports holding and movement of ball 12 among one or more positions within housing 101 or otherwise according to the disclosure. For instance, in at least one embodiment, insert 114 or a portion thereof can have a height in the range of 10-90 percent of a corresponding ball height, such as in the range of 20-80 percent or 30-60 percent of a corresponding ball height. Embodiments of ball dropper 100 having an insert 114 height less than 10% or greater than 90% are also possible.

As another example, opening 115 can be or include a shape other than cylindrical. For instance, opening 115 can have a cross-sectional shape such as triangular, square or another shape. Further, opening 115 can but need not be or include a though hole. For example, in at least one embodiment, opening 115 can be or include a partial opening or cavity, such as a semispherical or otherwise shaped receptacle for holding a ball 12 in one or more positions. As yet another example, in at least one embodiment, insert 114 can have a height less than a height of ball 12 and opening 115 can have a major dimension smaller than a major dimension of ball 12. Further, in at least one embodiment, opening 115 can have or include tapered walls (e.g., from top to bottom) for receiving and holding at least a portion of a ball 12, such as by way of being funnel shaped, which can but need not include being or including a through opening in insert 114.

In at least one embodiment, including but not limited to an embodiment having an insert 114 with a height less than a height of ball 12, housing 101 can include one or more windows 116, such as an opening or other transparent (or at least semi-transparent) viewing area, for allowing a user to see at least a portion of the interior 118 of housing 101 during operation of ball dropper 100. For example, a window 116 can be disposed in an end 120 or other portion of housing 101, such as the top, bottom, or one or more sides, separately or in combination, in whole or in part. In at least one embodiment, one or more windows 116 can advantageously allow for a user to visually confirm whether a ball 12 is present in housing 101 or insert 114, such as to verify successful loading of a ball 12 from first tube 102 into insert 114 or successful drop or passage of a ball 12 from insert 114 into second tube 108. Similarly, in at least one embodiment, ball dropper 100 can include one or windows 116 in one or more other portions of ball dropper 100, such as first tube 102 or second tube 108 (see, e.g., FIGS. 6-7).

In at least one embodiment, ball dropper 100 can include an insert 114 having a plurality of openings 115 of the same or different sizes, separately or in combination, in whole or in part. For example, insert 114 can be adapted for cooperating with balls 12 of different sizes, which can include separately, optionally or simultaneously. As illustrated in the exemplary embodiment of FIGS. 3-4, which is but one of many, in at least one embodiment, insert 114 can include one opening 115 having a diameter or other major dimension d1 and one or more other openings 115 having one or more respective diameters or other major dimensions d2 (et seq.). In at least one embodiment, dimensions d1 and d2 can be the same. In at least one embodiment, dimensions d1 and d2 can be different, such as for optionally being used for balls 12 of different sizes or dimensions. For example, in at least one embodiment, insert 114 can be removably and reversibly or otherwise changeably coupled with housing 101 and/or one or more other components of ball dropper 100 (e.g., actuator 128 further described below) and can have a first opening 115 of dimension d1 and a second opening 115 of dimension d2. Insert 114 can have a position wherein the first opening 115 is operable to receive a ball 12 of a size corresponding to dimension d1 and another position wherein the second opening 115 is operable to receive a ball 12 of a size corresponding to dimension d2. In this manner, a user can optionally configure ball dropper 100 for cooperating with balls 12 of different sizes as needed or desired for an implementation of the disclosure, such as by reversing or otherwise changing the position of insert 114 relative to housing 101 or another component of ball dropper 100.

Similarly, in at least one embodiment, ball dropper 100 can include one or more adapters 122, such as a tube insert or reducer, for reducing or otherwise adapting a ball flow path in a tube or portion thereof for a ball of a particular size, which can be any size according to an implementation or application of the present disclosure. In at least one embodiment, for example, ball dropper 100 can be adapted for cooperating with balls 12 of different sizes and ball dropper 100 can include one or more adapters 122 for changing an internal diameter of at least a portion of one or more tubes or other ball paths, such as first tube 102, second tube 108 or one or more openings 115 in insert 114, for cooperating with or better cooperating with one or more ball sizes according to an implementation of the disclosure. For instance, in at least one embodiment, first tube 102 can have an internal dimension d3 that can define or limit the maximum ball size that can pass through first tube 102 according to an implementation of the disclosure, which can be any ball size, such as an internal dimension at least slightly larger than such maximum ball size. While a relatively smaller ball 12 may also pass through a first tube 102 having internal dimension d3, in at least some cases it can be advantageous to at least partially limit lateral movement of a ball 12 within first tube 102 (e.g., for helping ensure accurate delivery of ball 12 to housing 101 or insert 114) and adapter 122 can be coupled to first tube 102 for at least partially reducing the gap or size difference between an exterior dimension of a ball 12 and internal dimension d3.

As illustrated in the exemplary embodiment of FIG. 3, in at least one embodiment, adapter 122 can be or include an adapter tube 124 adapted to be disposed at least partially within first tube 102 and having an internal dimension d4 adapted for use with a relatively smaller ball 12 in comparison to internal dimension d3 of first tube 102. Adapter tube 124 can but need not have a length greater than or equal to the length of first tube 102. In at least one embodiment, adapter 122 can include a coupler 126, such as a flange, cross-piece, shoulder or stop (which can but need not be or include one or more fasteners) for supporting coupling of adapter 122 or adapter tube 124 to first tube 102. For example, in at least one embodiment, adapter 122 can be disposed in first tube 102 and held in place by gravity and coupler 126 can be a structure larger than internal dimension d3 or otherwise adapted for preventing or limiting an extent to which adapter tube 124 can be disposed into first tube 102. As another example, in at least one embodiment, coupler 126 can be or include a mechanical fastener or mechanical fastening means (e.g., threads, pins, quarter-turn locking connections, flanges configured to be bolted or screwed together) for more securely fixing adapter 122 in place relative to first tube 102.

While adapter 122 has heretofore been described with reference to cooperation with first tube 102, in at least one embodiment, ball dropper 100 can include one or more adapters 122 for similarly cooperating with one or more other components of ball dropper 100, such as insert 114 or second tube 108. For example, ball dropper 100 can include one or more adapters 122 for coupling with second tube 108 to reduce an internal dimension d5 along all or a portion thereof. As another example, bd 100 can include one or more adapters 122 for coupling with insert 114 to reduce an internal dimension d1, d2 along all or a portion of one or more openings 115. In at least one embodiment, ball dropper 100 can include a plurality of adapters 122 of different sizes, such as a kit or set of interchangeable adapters 122, for optionally configuring an implementation of ball dropper 100 to cooperate with one or more different ball sizes as may be needed or desired during well operations.

In at least one embodiment, ball dropper 100 can include one or more actuators 128 for moving one or more inserts 114 between or among one or more positions, such as one or more positions relative to housing 101 or tubes 102, 108 for receiving or dropping a ball 12. Actuator 128 can be coupled to or relative to housing 101 in one or more positions and, in at least one embodiment, can include both static and dynamic components, such as an actuator housing and/or mechanism 130 for moving an actuator arm 132 or other movable actuation component between or among one or more positions. For example, ball dropper 100 can include one or more actuator supports 134, such as a plate, cage, platform or mount, coupled to one or more other components of ball dropper 100 for holding actuator 128 in one or more operable positions relative thereto. Actuator support 134 can but need not be a portion or component of housing 101. In at least one embodiment, actuator support 134 can be sized and arranged for having actuator 128 coupled thereto removably or otherwise, such as by way of one or more fasteners (e.g., screws, bolts, pins, etc.). Actuator support 134 can but need not at least partially enclose actuator 128, such as for protection from one or more potentially damaging conditions of a surrounding environment (e.g., water, temperature, contaminants, moving equipment, etc.).

Actuator 128 can be adapted for selectively moving insert 114 among one or more positions, such as a first or other position for disposing an opening 115 in ball receiving communication with first tube 102 (see, e.g., FIG. 3) and a second or other position for disposing opening 115 in ball dropping communication with second tube 108 (see, e.g., FIG. 4), such as for introducing a ball 12 into second tube 108. Insert 114 can be coupled to actuator 128 or a portion thereof, such as actuator arm 132, for supporting such movement, directly, indirectly or otherwise. For example, in at least one embodiment, insert 114 can have one or more ends 136 (or sides, etc.) adapted for coupling with an actuating end 138 of actuator arm 132, whether removably or otherwise. Insert 114 can be coupled or couplable with actuator arm 132 in any manner according to an implementation of the disclosure, such as threadably, via one or more fasteners, or otherwise. For instance, one or more ends 136 of insert 114 can include female threads and actuating end 138 of actuator arm 132 can include male threads and actuator 114 can be threaded onto actuator arm 132 in or to one or more linearly fixed actuating positions relative to actuating end 138. In other words, by rotating insert 114 one direction or another (e.g., clockwise or counterclockwise), insert 114 can be adjustably positioned relative to one or more components of actuator 128, which can help dispose insert 114 in a position for proper alignment with tubes 102, 108 during ball dropping operations. Mating threads are but one example of many possible structures for coupling insert 114 and actuator 128; any manner of coupling can be used according to an implementation of the disclosure. In such embodiments, insert 114 can but need not be adapted for coupling with actuator 128 prior to being disposed in housing 101, such as for allowing insert 114 and actuator 128 to be positioned relative to and coupled to housing 101 and/or one or more other components (e.g., actuator support 134) as a single unit. However, this need not be the case and, in at least one embodiment, one or both of insert 114 and actuator 128 can be adapted for coupling with housing 101 and/or actuator support 134 prior to being coupled with one another.

As another example, in at least one embodiment, insert 114 need not be attached to actuator 128 in a temporarily or otherwise fixed manner. For example, insert 114 can be slideably disposed in or otherwise moveably coupled to housing 101 and ball dropper 100 can include one or more springs (not shown) or other biasing devices for biasing insert 114 in one or more directions, such as toward actuator 128. For instance, one or more springs can be disposed between insert 114 and a barrier 140 within housing 101 or, e.g., at end 120 of housing 101, and actuator 128 can be adapted for pushing insert 114 against the force of such a biasing device during actuation, which force can be sufficient to return insert 114 to one or more positions (e.g., in alignment with first tube 102) following actuation. In such an embodiment, and in other embodiments, barrier 140 or end 120 of housing 101 can be at least partially open or openable for allowing access to insert 114, whether for maintenance or otherwise.
